About Z76.4
Z76.4 is the ICD-10-CM diagnosis code for other boarder to healthcare facility. It belongs to category Z76 (persons encountering health services in other circumstances), block Z69-Z76 (persons encountering health services in other circumstances) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z76, choose Z76.4 (Other boarder to healthcare facility) only when documentation doesn't support a more specific option: encounter for issue of repeat prescription (Z76.0), encounter for health supervision and care of foundling (Z76.1), encounter for health supervision and care of other healthy infant and child (Z76.2), healthy person accompanying sick person (Z76.3), Malingerer [conscious simulation] (Z76.5) and persons encountering health services in other specified circumstances (Z76.8).
Don't report Z76.4 together with the conditions in its Excludes1 note: homelessness (Z59.0-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as V65.0 (healthy person accompanying sick person).
